A simple soil water balance model to estimate groundwater recharge in the dry zone of Sri Lanka



A simple soil water balance model to estimate groundwater recharge in the dry zone of Sri Lanka



Tropical Agricultural Research and Extension 3(2): 120-126



Estimating the rate of recharge is essential in developing the groundwater resource. The soil water balance of the root zone is a simple method of estimating recharge. This paper analyses the important components of a soil water balance and determines the essential components of the water balance equation for the dry zone of Sri Lanka to estimate recharge. The essential components include interception, runoff, and preferential flow.
